Subject: [Qemu-devel] [PATCH] blockjob: drop block_job_pause/resume_all()
Date: Tue, 24 Apr 2018 09:52:40 +0100 [thread overview]
Message-ID: <20180424085240.5798-1-stefanha@redhat.com> (raw)
Commit 8119334918e86f45877cfc139192d54f2449a239 ("block: Don't
block_job_pause_all() in bdrv_drain_all()") removed the only callers of
block_job_pause/resume_all().
Pausing and resuming now happens in child_job_drained_begin/end() so
it's no longer necessary to globally pause/resume jobs.
